That said, is there any data on browser share with JS turned off? Because I'm sure I'm being obtuse, and I know I can be accused of being a dick, but I doubt I would care very much.
My company makes mobile games. We don't support below Android 4, we don't support below iOS 6. Not allowing JS completely is absurd, IMHO, and much like expecting developers to continue to support IE 6. It's 2015, JS is the programming language of the browser-based Internet, and expecting developers to cripple their own applications to support a vanishingly small amount of people that block JS may simply make no sense, economically speaking.
Not to get too much on my high horse, since you're clearly in an area where there's no way you could ever support vision impairment, the problem with ignoring vanishingly small portions of an audience is that the same people tend to be in that portion all the time and never get anything. For apps that aren't expecting interactions more than every ten seconds, it's so easy to just give them flat HTML.
In any case, I'm definitely for making a site mostly accessible (I've encountered edge cases where it is weird) and if current screen readers support most JS, then I'd test for accessibility, not necessarily all-stop lack of JS.
I expect some sites not to work fully, but completely blank is unexpected.
We originally built this as a page on openlistings.co (/fixers), but then found this awesome domain. The assets are all the same from openlistings.co, we're just checking the current domain in our Backbone.js router. Kind of hacky, but it was the quickest way to get it up! Also, if you click any of the detail pages you need the rest of the assets anyway because it takes you back to openlistings.co. Long story short, it's pulling in assets and doing API calls to openlistings.co.
Like I said, I expect some things not to work. But the page should not be completely blank.
The plain text on the home page does not need javascript for anything.
It is a webapp, those require javascript. The fact that you do not like it is not really relevant.
Ludits cannot be allowed to stop progress.
It was a convenient short-hand for many things but it's not very reliable in that regard any more.
This site seems fairly solid at first glance so personally speaking I'm not the slightest bit bothered that it doesn't work with javascript disabled.
I expect sites sometimes not to work fully. But completely blank?
